The time taken to achieve a specific strength is an important economic and design parameter in high strength concrete construction. In fact, a high early strength may bring far more practical and economic benefits than a high strength at a later age, in terms of early removal of formwork, increased productivity of precast units, early transfer of pre-stress, and early application of service loads.

High Performance Concrete - an overview | .

Besides the production of high-performance concrete, superplasticizers are also commonly used in the production of high-workability concrete. With a slump value of 180–230 mm, high-workability concrete can be pumped rapidly over long distances, easily compacted in structures with highly congested reinforcement, and can even be self-compacting (i.e., requiring no external compaction effort).
